The 20-year-old rookie Nasir Jones released his debut album Illmatic on April 19, 1994. We can argue all day about the greatest rap album of all time, but Illmatic is usually the first name that will come up in that conversation. Today is the 30th anniversary of Illmatic, and Nas has used that moment to announce something that fans have wanted for a very, very long time: His long-promised collaborative album with DJ Premier is finally happening this year.
